Question: One method used to produce hydrogen as a fuel decomposes methanol in the reaction CH 3 OH(l) 2 H 2 (g)+ CO(g). (a) What

One method used to produce hydrogen as a fuel decomposes methanol in the reaction CH₃OH(l) → 2 H₂(g) + CO(g).

(a) What is the standard reaction enthalpy of this process?

(b) What is the standard enthalpy of combustion of the hydrogen produced in the reaction?

(d) Which process generates more heat at constant pressure, the direct combustion of methanol in part (c), or the two-step process (parts (a) and (b) combined)?
